Your statement was "There is a large, almost exclusively muslim criminal element there ..."
That's pretty inflammatory. You stated this as fact when it appears to be your subjective opinion.
I am genuinely interested in data to support that claim since it is counter to my own experiences having lived 10 minutes from there for years and daily follower of the Danish and International media.
Taking that one incident does not prove your statement. "One swallow does not a summer make."
